SNF have to transfer from spent pool in the plants to another area by using the safety way. Handling and transportation of SNF are common key processes for the SNF management. During this activity, SNF is required to evaluate structural integrity by using the proven evidences of the tests or other reliable methodologies. The SNF test, however, is accompanied by very high cost and safety issues because of handling irradiation object. Alternatively, the computational methodologies(ex: Finite Element Method, Numerical Method, etc.) are usually employed as a technical solution based on the information of other effects. In this paper, the simulations for analyzing the fuel integrity is conducted by using verified finite element model during the regulated normal and postulated conditions. At first, the model is designed as the many beam elements considering full size. Second, the verification process was performed for having the mechanical properties and dynamic characteristic at the model. At the end, SNF drop was simulated at the several conditions. In the result of this paper, SNF has stress within elastic zone at 0.3 m drop but SNF is expected to be damaged result from free drop simulation of 9.0 m.
